To all 'whom 'it may concern:

Be it known that I, HENRY CLAUDE'P'RI- vn'rr, a citizen'of the United States, ,residing at Los Angeles, in the county of Los Angeles and State of California, have in' 'exited anew and useful Continuous Agita-ting'Cooker, of which the following is a specification. l

This invention relates to cookers in which the substance to-be cooked is stored in' cans and cooked while in such cans, the cans being passed through cookers. I

An 'object of the invention is to provide a cooker of this class in which a very high degree of temperature can be maintained.

Another object is to provide a cooker in which a, large knumber of cans may be cooked 'simultaneously and in which each can will be 'fed into and removed from said cooker without interfering with any of the'other cans in said cooker. A

A still further object of the invention is to provide an arrangement whereby the cans are fed through the cooker at such a speed that the substance to'be cooked will simultaneously be properly cooked and fed ont so that they will be lready for the Warehouse.

Another object of the invention is vto provide an arrangement whereby the substance in the cans will be agitated while being cooked. '.lo this end, the cans are carried through tlul cooker while on their sides and thus pelniittlal to roll.,

Another object of the invenion is to provide an arrangement in which the cans are autonmtieally fed into thccooker.

' Another object of the invention is to provide a cooker having a conveyor to convey :ans through a steanrchcst, which conveyer may, beremoved bodilyt'roni the stcain'chest for the purpose of repair, cleaning and the like. f

The telescopic guide-way consists of an upper section 100 mounted to slide in the lower section 101. The upper end 102 ot' the upper section 100 has a slight outward flarev as it curvesI one-quarter ot' a revolution around the idler 9T, brackets 103 being Secured around each side of the upper section 100 which brackets are mounted upon a shat'( 101 radially inward oli' said upper end on which shaft the idler 9T is mounted. The shaft 101 is carried by side rollers 69 running upon a track T71 secured to the framework 49 at each side of the take-up and extending longitudinally of said frame work to act as a horizontal guide for the upper end ot' the telescopic guido-way. Connected` to the shaft 101 is avoke 105 to the end ot' which'is secured a cable 100, which extends longitudinally toward the rear of the chest 1 where. it passes mounted on a shaft 10S secured to the frame work 49 in the chest` the cable 100 having a weight 109 secured to its end, by means ot' which the cable 100 exercises a continual pull on i ie top o1' the, telescopic,guide-way 9S to move the shaft 104- along in the track 771 and thereby draw the guide-way 98 to- 'ard it and by so doing lirst sliding vthe section 100 into the section 101 when it is forward ot its vertical position and sliding the section 100 out of the section 101 when the guide-way inclines rearward o1 its vertical position. ln this way the slack in the cable SS will be taken up. The lower end 110 oi the lower section 101 is siniilarly curved one-quarter of a revolution around its idler 00,1111 brackets 111 being secured around each side of the lower section 101 and supporting:r a shaft 112 between them on which theidler 99 is mounted, the shaft 112 being mounted in bearing brackets 113,secured to the set of posts 53, in the present instance the second set of posts from they front of the chest. By reference to Fig. 1, it will be seen that the idlers 97 and 99 operate in a plane that lies longitudinally of the chest 1 and between tne two directions of tracks,

'lhe sections 100 and 101 form guideways for the cable, said gnide-ways comprising.` two inclined side sheets 114 extending ufnvard and outward awayvtrom the floors hood 123 is hinged7 having over an idler 10iof the sections and secured to theyloors of the sections respcctively.

The cans 115 to be carried through the cooker are placed on their sides and carried by the cable 8S, the cans being spaced apart rom one another by means of pins 116 which are fastened lto the cable at equal intervals along the same. To accommodate the pins 116 when passing around the various sheaves and idlers, these sheaves and idlers are provided with recesses 117 spaced apart a distance corresponding to the distance between two successive pins 116.

At the entrance to the chest 1 there is provided a special feeding sprocket 67 which cooperates with a tunnel 11S to feed in one can between each two successive pins 116. The tunnel as illustrated in Figs. 1, 2 and 3 has su]. poi'ting irons 11.9, one secured to each straight side 19 of the entrance chute, the two irons 119supporting between them the stationary h'ood 120, the forward end of the roof 121' ot said "hood 120, being pro vided with a hinge 122 to 'which a movable straight sides 121, a n upwardly inclined roof portion 125 extending forward and upward a short distance from the hinge that is parallel to the short. roof portion 125 and spaced apart from the root' portion just sullicient to permit a can to pass between the two, a substantially horizontal floor portion 12T being united with the floor portion 126 which floor 12T contacts with the lower edge 128 ot the openine' 2l whereby the tunnel 11S `is su i )orteil when in feedine' iosition. The

sprocket- (i has an internal sheave member 129 formed substantially like tl i sheaves 81 ha ving vrecesses 11T ridges 130 on each side ot the cable-receivinggroove 1251 being practically equal. On each side of the sheave member 129 isv se` cured a feeding' sprocket disk 132. The sprockets ot' the two disk members are parallel with one another, and have a forward .tace 131 that is concave and a `rear face 122 and having a floor 126.

for the pins 11G, the

135 that is convex, the arrangunent of sprocket disks 132 relative to the sheave member 129 being` such 'that each pin 110 of the conveyer cable S8, will, as such pin passes around on the sheave member 129,

.project out just rcarwuirdl)7 of a concave face 134 and alongside ot' a convex face 135 so that a can may be received by thetwoparallel concave faces 131 with a pin 110 engaging the can 115 at its rear by means of which the cans will be passed on to the track with a conveyor cable pin 110 at its rear. The sprocket 07 and tunnel 11b` prevent piling up of the cans onto the conveyer cable and track since only one can pass between the inclined lloor 126 and root. before the nextsuccceding can 115 vis permitted to pass onto the concave faces 13-1, the convex faces 1.35 projecting outward may - the' course of travel.

ward movement of the pins,which rise above the floor 126 and hold the succeeding can on the loor 126 until the suc-4 ceeding concave faces"134 rise up.

The forward portion of the tunnel l118 is nby means of which ready access is permitted to the feeding sprocketv 67 and theretoconnected parts.

The cable is arranged to travel just under and between the side-rails of the track with the cable pins 116 extendingup between the horizontal legs of the -track rails 81, 82 to roll the' cans along said legs, see Figs. 6 and 7 and in the present instance the pins 116 comprise similaihalf sections, each of which has a cable gripping groove137, said sections being gripped fin position upon the cable by means of upper and lower bolts 139, the upper :bolt passing through cable supporting lugs 138 uponr the outside of each of the pin sections.

Vzontal legs of the siderails 81, 82 during On the pins 116 yare provided shoulders 140 to prevent" any upders together with the lugs 138 maintain the cable in accurate alinementwith the end sheaves.

In the operation of `the device, .it will be `seen that the cans passed in at the entrance will each be securedbetween two pins 116,

most sheave '84 the cans lying ontheir sides upon the horizontal .legs of the tracks so that they may be rolled `therealong by the tips 141 or the pins to agitate the food stuifs contained therein, the side walls of the tracks between which the cable passes serving as guides to maintain the cans ,in-. position over sai cable.

The opening 12 -at the upper end of4 the doorv 9 serves as an exit or discharge for the cooker. The opening 12 is positioned above the curvedA sheet 83 and opposite the topso that a chute 142 may be Secured adjacent the topmost shcave 84 and supported on the lower edge of the opening 12 to receive the cans passing on to the topmost sheave 84 the l ischarge o )ening has side Walls 1l43 and a lsloping floor 144 fastened to the side walls, the inner one of said walls being provided with a side opening 145' through which the cable pinspass upon `their way out of the chute and around the topmost' heave 84. A portion of the Hoor is cut away to accommodate thetopmost heave 84, leaving the aslant edge 146 12. The chute 142 whichextends from the side opening 145 at i' one siie tolthe abutting othei7side. When thefood stuffs heing'cooked do not require to be passed through the entire track angle 82 aglithe As the cable moves along betweenthe rails it is supported b y these lugs 138 whichslide upon the horiand feed them out through.`

cooker, the cans containing such food stuffs may-be switched oil or d ischarged from any one vof the lower .sheaves according length of time the -food stuffs require to, be cooked. For this purpose the curved sheet 88 may be provided with openings 147 .one above the other and each o iposite a sheave y84, as shown at the right o Fig. 1. Opposite these openings 147 the door 9 is provided with discharge openings 148 similar to the discharge opening 12 already described, and when it is desired to discharge the food stuffs through one of these lower sets of openings, it is only necessary to secure a chute similar to the.chute 142 in place through. such set of openings. discharge openings 147 vand 148 are provided with doors 149 and 15() respectively, composed of substantial material andsuitably lined, the doors being fastened in place when desired by any suitable means such as the studs 151.

It is obvious thatV various changes and modifications may he made to the details of construction without departingA from' the broad scope of the invention.
